Hi, I am running Katalon test using Console mode and my test suite contains 4 tests. However I have observed that after execution completes (My tests have failed) katalon studio report is prepared and is console is closed but it left 4 Chrome instance in task manager consuming more than 90% of cpu. Anyone observed similar issue? ---

There is a setting where you can make Katalon clean up after running, project\> settings\> execution\> default. That seems to do it for me ---

That settings only terminate chromedriver.exe. Please ensure you’ve called ‘Close Browser’ keyword also at the end of your test, otherwise Chrome.exe still exists until you call this keyword ---

It happened with specific chromedriver.exe verison only. After update of Katalon 5.4.2, it’s working fine. we can close this thread ---

Chrome.exe processes are left open . ChromeDriver.exe are doing the same. Running from command line also adds “Conhost.exe” on the build agent. 100% CPU on the runner pc ---

I also have this issue on my machine. To workaround it, I created a .bat file that looks like this: taskkill /f /im chromedriver.exe taskkill /f /im chrome.exe pause I run it after long Katalon sessions to free up memory. ---

We’re seeing similar behaviour using Katalon Studio 6.3.0 (Beta) / Win 10. Particular instances/tasks that aren’t being closed after a scheduled task are: - chrome.exe - chromedriver.exe - conhost.exe - katalon.exe Taskkill commands don’t appear to work for conhost.exe and katalon.exe. ---
